Here see if this helps. Sorry for the water marking on the graphic but I've had some issues with Chinese kit makers stealing my plans and making a quick buck off of them. Some of the original idea came from my first FPV plane Aerosodle. Qrome had a good idea with his QTB plane over in the AP forum.

The front one has a slot for the boom to go into. You then bolt the boom into place on the front boom holder. The back boom holder just holds things in place. I guess I could draw out a more detailed boom holder if everyone was interested.

i agree, definatly strengthen up those boom's. looks like it's going to be fun. I just built a p-38 lightning. thinking of throwing one of our extra fpv set on it. i want to fly it first though. stupid winter is ruining all our fun

The motor is mounted very close to the CG. The prop is between the twin booms. It helps cut down on weight IMHO... If EDF was a bit more efficient I'd pick one up, mount the fan slightly behind the CG, and go with that.. I have a fan from an old EDF plane.. It's just finding the time to build out a new plane for the Fan! *The time!! The time!!*

It would be nice if there was a EDF BL outrunner(maybe there is ). I put my FPV gear in my Twister EDF and I loved the sound it makes through the headphones. Made it seem like I was really flying fast .
